Matthew 9:35-38

35. Jesus went through all the towns and villages, teaching in their synagogues, preaching the good news of the kingdom and healing every disease and sickness.
36. When he saw the crowds, he had compassion on them, because they were harassed and helpless, like sheep without a shepherd.
37. Then he said to his disciples, "The harvest is plentiful but the workers are few.
38. Ask the Lord of the harvest, therefore, to send out workers into his harvest field."
